perl edit file
Is there a way to edit a file without opening two files
the only method I know is
one file for reading from
and one file writing to

I cannot think of any other ways

Open the file, read it's complete content, truncate and overwrite.

Code:
open(FILE,"<","filename")
@file=<FILE>
close(FILE)
open(FILE,"<","filename")

pattern here
print FILE "dfksdfjsdkfj\n"
close(FILE)

You are openning the file in read mode at second time.
This should not write to file.
